North Korea's claim on Friday that it had launched a new type of tactical short-range ballistic missile highlighted military advances by the nuclear-armed state and propelled it to the top of new U.S. President Joe Biden's foreign policy agenda.
The United States condemned Thursday's launches, which came hours before Biden held his first White House press conference since taking office in January.
When asked if he agreed that North Korea was the top foreign policy issue he faced, Biden replied: "Yes."
